[Chimera-users] Transparency of ribbons

[lvyuan zhang]

Hi all,
       I'm a new user and my question maybe a little weird to you guys. I want to make some parts of my protein, let's say "A",  partially transparent, so when compared to other parts of the protein, let's say "B", these "A" parts are hardly visible (the background is white). So I set the alpha value of "A" to less than 1, such as 0.1. then I save the image with POV-ray. The resulted "A" is too dark, and it is still quite "visible". Is there any way to make partially transparent ribbons lighter, instead of darker than non-transparent ones?
     I would really appreciate it if any one can help resolve this problem. Thans!

Cheers!
Luyuan Zhang
